WINDOW VENTILATOR.

Application led January 26, 1928.

This'invention relates to new and useful improvements in windowventilators, and aims to provide an improved ventilator that is builtdirectly within the window frame so that air may pass into and from aroom while the window is completely closed, the

structure being further such that flies or insects or other foreignmatter cannot pass into the room from the outside. Furthermore, floheavy drafts of wind will be prevented, and

due to the structure of the device snow or rain cannot enter even thoughthe ventilator be in open position.

One of the most important objects is the provision of a ventilator ofthis character that may be built directly into a window frame withoutmaterially increasing the cost of the window and without interferingwith the proper fitting of the window or the opening or closing of thesame within the buildingvframe.

ith the foregoing and other objects in view as the nature of theinvention will be better understood, the same comprises the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the accompanying drawing wherein like reference characters indicatecorresponding parts throughout the several views:

' Figure l is a fragmentary inner side elevation of the lower end of asliding or swinging window sash, the frame of which is constructed inaccordance with the present invention.

Figure 2 is a detail longitudinal section taken substantially upon theline 2--2 of Figure l, the ventilator being disclosed in open position,and

Figure 3 is a similar fragmentary view disclosing a ventilator asclosed.

New having particular reference to the drawings, 5 designates the frameof a sliding or swinging sash, the lower frame bar of which is formed inthe present instance with spaced longitudinally extending circularopenings 6.

Arranged upon the inner side of the lower Vmember of the sash frame isan elongated `strip 7 of wood or other .suitablematerial lto beunderstood that some changes may be ySerial No. 249,661.

that is also formed with longitudinally spaced circular openings 8adapted for registry with the openings 6 in the window frame asdisclosed in Figure 2. This strip 7 is 55 preferably of laminatedconstruction, while arranged between the laminations is a length of finemesh screen 9 to prevent the passage of insects, or large particles ofdirt throughthe openings 8. 60

I At opposite ends of this strip 7 the same is formed with .elongatedslots 10-10, while arranged through said slots and secured to the frame5 are pins 11-11 that secure the sliding strip 7 in close relation withthe 65 frame 5, and at the saine time permit the longitudinal movementof the strip from the open position disclosed in Figure 2 .to the closedposition disclosed in Figure 3. Obviously, when the strip is arranged inthe position indicated in Figure 2, the openings in the sash frame 5 andthe strip are in registration so as to permit the air to enter or 'leavethe room whereas when the strip is moved to the position indicated inFigure 3 the openings are out of registration to close the passagesthrough said window frame.

Said sliding strip 7 is equipped intermediate its ends with any suitablecharacter of operating handle or knob 12.

In view of the foregoing description when considered in conjunction withthe accompanying drawings it will be apparent that I have provided ahighly novel, simple and useful window ventilator that is well adapted yfor all the purposes heretofore designated, even though I have hereinLshown and described the invention as consisting of certain detailstructural elements it is nevertheless made therein without affectingthe spirit and scope of the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is In a window ventilator of the characterdescribed wherein the window frame is formed with spaced longitudinalopenings, a pair of pins secured to the window frame at opposite ends ofthe openings, a strip of material arranged upon the inner side of l thewindow frame within the contines of said openings and havinglongitudinal slots at its opposite ends through which said pins projectwhereby said strip may be slid longitudinally upon the Window, saidstrip having spaced openings therein for registry with the openings inthe window frame when the stripl is moved into one position, said stripbeing of laminated construction, and a length of Wire screening arrangedbetween the laminations for preventing the passage of 10 foreign matterthrough the openings in said strip. In testimony whereof I aHiX mysignature.
